TYPE-WRITING MACHINE.

Specification of Letters. Patent.

' Application filed September 80, 1907. Serial No. 395,1 59.

To all whom it may concern:

Be it known that I. Annxnxnnn H. Vonn- MAN, a citizen of the United States. and

resident of Omaha, in the county of Douglas and State of Nebraska, have nvented certain new and useful Improvements in Type- Writing -Machines, of which the following is a specification.

M.y -1nvent1on relates to the right-hand margin stops of typewriting machines and hasfor its main object to provide a single stop block with two differently located stop faces for arresting'the return movement of the carriagepso as to enable the operator to indent the work and begin the lines at either of two pointsffixed relatively to each other,

and my invention consists in the features of construction and combinations of devices to be more fully described and particularly pointed out in the appended claiins.

-In the accompanying drawings, Figure 1 is a sectional elevation .of so much of a Monarch typewriter as'is necessary to illustrate my invention, and to which style ,of machine my invention has been applied in practice. Fig. 2 is a fragmentary' front elevation of the carriage, the longitudinal stop bar and the compound marginal stop arranged pthereon.

' desi In both mo e same part will be found ated bythesamenumeral of reterence. 1 esignates the paper carriage which as usual .in the Mon arch machine comprises a gin stop' bar 4 the stop bar, and the bloc back bar with top and bottom V-rails which run on roller bearings 2, there being mount.-

ed on the framework opposing rails 3 hav'ing corresponding ll-grooves.

Supported upon the 'upperrailS is.;a mar formed on its front edge intermediate spaces 5 for in sto at any desired posiar. he compound margiwith teeth and holding the mar away on itsunderside to artiallyembraoe is formed with an opening for the "reception and workirilg of a spring pressed catch or ,dog Tfor hol of the catch entering on ing the block securely on of; the jspa'ces. 5

between theteeth on the bare, its-common.

i'n' the' Monarch machine.- .The'jstop block is, however,-otherwise difierently constructed stop faces or lugs and :9, the lug 8 -being chi ne, as indicated at 16, and a 4 Located upon the 1 both of the stop lugs carriage stop 19 said-rod, one part 'erator innermost ornearer the center of the mafittenteol Ja 3,1911;

chine and the lug 9 being: outermost and which is attached a vertical connecting rod 11 whose lowerend is attached toth'e rear-.

wardly projecting arm 12,, of a bell lcrank.

ward end with a key or button l5,'the forward-end of the rod being mounted to slide To the upwardly extending arm 13 of said bell crank is pivotally connected the rear end of a push rod 14 provided at. its, for-J in hearings in the framework of the mabeing provided to return these parts tomormal position. The ends of the margin stop bar being mounted on pivots 17 it-is adapted to be oscillated by the connections just de scribed and for explained. I I

carriage and pivoted thereto at 1 8 is a lever or arm 19, the upper end ozt which is adapted to contact with spring 15', i

a purpose presently 'to be 8 and'9 to arrest the i return movement of the carriage. In frontof the stop member 19 is an abutment 20 for preventing'the stop member fromtilting,

toward the left when it contacts with the stops 8 and 9. 3 The stop member 81is beveled on its under side as at 8. vertical. stop faces of preferably equal to about three letter spaces and the downward ex need be far enough only to engage with the when the stop 8 is'tilted' upwardly to an inoperative position. The stop .8 arrests the carriage, say; at the normal marginal. position, I v to indent withm the mar inal field, theoperato'r with one hand pus es backthe ma'ra gin release button 15', thus tiltin The distance between the tension of the lug. 9-

, 3 the lugs 8and 9 is gin stop bar and raising both to sto s 8 and 9 simultaneousl the stop-8 going igh enough to enable't e carriage stop 19 to pass by it and then to strike the inner .face of the ower portion pulls the carriage toward the right. when desired, the carriage may be of .theistop 9 as the op stopped uniformly at, say, three letter space distances to the rightof the normal sto ping position so that the work may be in ented within the marginal field at the left-hand side of the sheet in this fashion MCMCMCMCMCMCMCMCMCMCMCMC MGMCMCMCMCMCMCMCMCMCMCMC momomcmcmcmonouononcnc MCMCMCMCMCMCMCMCMCMCMCMC MCMCMCMCMCMCMCMCMCMCMCMC mcmonomcmcnomcncncmcmc Of course, if desired, the two stops 8 and 9 may be fixed apart any given number of letter spaces instead of the three preferred and illustrated herein.

I have found in practice this construction of marginal stop to be especially useful to court reporters, authors, architects, engineers and the like, desiring to print marginal indentations within the usual fixed margin at the left-hand side of the sheet.

It will be observed that the relative positions of the two stop members are fixed or unchangeable and .hence the indentations may be made with uniformity and without undue loss of time. Another advantage is that the two" stops are adjustable bodily together without losing their relationship with respect to each other, both being mounted upon the same block and movable simultaneously therewith to any desired position on the stop bar.

What I claim as new and desire to secure by Letters Patent, is

1. In a typewriting machine, the combination of a traveling paper carriage, a com pound margin stop for arresting said car- .riage'when pulled to the right by hand, said stop com rising av single block and two right-.han margin stops depending therefrom and fixed one relatively to the other for varying the beginning of the lines of writing, the outer one of said stops depending to a lower level than the inner one, and th; inner stop being beveled on its under $1 e.

2., In a typewrit-ing machine, the combination of a traveling paper carriage having a stop member, a margin stop bar, a righthand margin stop block adjustable thereon and carrying two depending right-hand margin stops fixed one relatively to the other for arresting said carriage when pulled to the ri ht by hand, a dog or detent for holding sai block and stops in the adjusted position, and means for tilting said stop bloclt and stops. 7

3. In a typewriting machine, the combination of a paper carriage provided with a stop member, a pivotally mounted stop bar, a stop block thereon provided with two stop lugs depending therefrom and having a fixed relation to each other, one of said lugs being in advance of the other and the outermostlug bein the longer of the two and depending to a' ower level, the carriage being adapted to be arrested normally when pulled to the right by hand by the inner and shorter lug, and means for tilting the stop bar and stop lugs upward so as to enable the stopping member on the carriage to pass by the inner and shorter lug and to be brought into contact with the outer and longer lug.

Signed at Omaha in the county of Douglas and State of Nebraska this 17th day of September A. D. 1907.
